13.93 is what percent of 81.12 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 81.12 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 81.12, so we can write it down as 100%=81.12.
4. We know, that x% equals 13.93 of the output value, so we can write it down as x%=13.93.
5. Now we have two simple equations:
1) 100%=81.12
2) x%=13.93
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=81.12/13.93
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.93 is what percent of 81.12

100%/x%=81.12/13.93
(100/x)*x=(81.12/13.93)*x       - we multiply both sides of the equation by x
100=5.8234027279253*x       - we divide both sides of the equation by (5.8234027279253) to get x
100/5.8234027279253=x
17.172090729783=x
x=17.172090729783

now we have:
13.93 is 17.172090729783% of 81.12
